Materials Data on EuIn3 by Materials Project

EuIn3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Eu is bonded to twelve In atoms to form a mixture of face and corner-sharing EuIn12 cuboctahedra. There are a spread of Eu–In bond distances ranging from 3.38–3.43 Å. There are two inequivalent In sites. In the first In site, In is bonded in a 4-coordinate geometry to four equivalent Eu and six equivalent In atoms. There are two shorter (3.24 Å) and four longer (3.25 Å) In–In bond lengths. In the second In site, In is bonded in a 4-coordinate geometry to four equivalent Eu and six In atoms. There are one shorter (3.24 Å) and two longer (3.25 Å) In–In bond lengths.

Materials Data on EuIn3 by Materials Project

EuIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Eu is bonded to twelve equivalent In atoms to form EuIn12 cuboctahedra that share corners with twelve equivalent EuIn12 cuboctahedra, edges with twenty-four equivalent InEu4In8 cuboctahedra, faces with six equivalent EuIn12 cuboctahedra, and faces with twelve equivalent InEu4In8 cuboctahedra. All Eu–In bond lengths are 3.33 Å. In is bonded to four equivalent Eu and eight equivalent In atoms to form distorted InEu4In8 cuboctahedra that share corners with twelve equivalent InEu4In8 cuboctahedra, edges with eight equivalent EuIn12 cuboctahedra, edges with sixteen equivalent InEu4In8 cuboctahedra, faces with four equivalent EuIn12 cuboctahedra, and faces with fourteen equivalent InEu4In8 cuboctahedra. All In–In bond lengths are 3.33 Å.
